Ex Deo are still working on the follow-up to the debut album Romulus, scheduled for a release somewhere in 2012. The band will enter the studio later this year.

According to a press release, the second opus entitled Caligula is set to feature the most intense "epic metal soundtrack" to come out in recent history.

Mainman Maurizio Iacono (also known from Kataklysm) added: "The album will once again have the honor of some elite guest appearances. The band promises an album that will shake the metal scene!"

Artwork and layout for Caligula will be handled by classic artist Seth (Septicflesh). Some song titles include "I, Caligula", "Burned to Serve the Nocturnal Light", "In War & Conquest/Roma Caput Mundi" and "Teutoburg (The Ambush of Varus) - Part 1".
